Rolex’s new Oys­ter Per­pet­ual Air-King per­pet­u­ates the aero­nau­ti­cal herit age of the orig­i­nal Rolex Oys­ter. The watch with a 40mm case in 904L steel fea­tures a dis­tinc­tive black dial with a com­bi­na­tion of large 3, 6 and 9 nu­mer­als mark­ing the hours and a prom­i­nent min­utes scale for nav­i­ga­tional time read­ings. It is equipped with Cal­i­bre 3131, a self­wind­ing me­chan­i­cal move­ment fea­tur­ing a Per­pet­ual ro­tor and boasts a power re­serve of ap­prox­i­mately 48 hours. The os­cil­la­tor has a blue Parachrom hair­spring that of­fers great sta­bil­ity in the face of tem­per­a­ture vari­a­tions and re­mains up to 10 times more pre­cise than a tra­di­tional hair­spring in case of shocks. It is equipped with a Rolex over­coil, en­sur­ing its reg­u­lar­ity in any po­si­tion.
